Procedure A is used when only an air bath is used to cool samples in preparation for viscosity measurement. Caution should be taken when handling mercury and mercury containing products. The success of the ATF correlation and the development of this test method has over zstm been applied to other fluids and lubricants such as gear oils, hydraulic fluids, and so forth. The turntable holds 10 test samples. Home Products Contacts Search. Paperless videographic temperature recorder with flash memory card.

SimAir™ Test Cells for ASTM D2983

A video chart recorder option -V to track possible temperature upsets, and asrm digital sample temperature display option -D are available for Model BV Procedure B is used when a mechanically refrigerated programmable liquid bath is used to cool samples in preparation for viscosity measurement. Block Bath for sample preconditioning, 20 test positions. Ample storage is provided inside the cold chambers for pre- cooling the insulated cell carriers.

No viewing window, but with digital sample temperature display. A digital, indicating controller with resolution of 0. A video chart recorder option -V to track possible temperature upsets, and a digital sample temperature display option -D are available for Model BV It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part d283 the standard.

The key factor in this improved precision is the superior temperature control of the sample as its viscosity is being measured. A digital, indicating controller with resolution of 0. The two chambers allow simultaneous conditioning of samples at the same or different temperatures for quicker data collection then with asrm one apparatus.

Recommended are at least 2 reference fluids for each atm test temp. A Windows based PC is required not supplied. Ample storage is provided inside the cold chambers for pre- cooling the insulated cell carriers.

Low temperature viscosity values obtained by either interpolation or extrapolation of oils may be subject to errors caused by gelation and other forms of non-Newtonian response to spindle speed and torque.

It is designed for those laboratories with a very light sample load and limited space and budget. Model BV has two air test chambers. Windows based PC proprietary software is capable of controlling two baths simultaneously.

This test method is used in a number of specifications. Model BV has an 28 cm 11 inch square, multipane, insulated window with fluorescent light for observation of the interior, with 28 sample capacity.

Procedure C is used when a mechanically refrigerated constant temperature liquid bath is used to cool samples by means of a simulated air cell SimAir 3 Cell in preparation for viscosity measurement.

The use of programmable liquid baths for ASTM D has been allowed since the first development of the test if the cooling profile meets the specifications of Annex A2 of the method.

Model BV is a compact, bench top unit with 6 sample capacity with digital sample temperature display.
